    basic FUNCTION
  • dopamine receptor D1,adenylate cyclase stimulating
  • involved in the control of vascular tone
  • specific role in spinal network activation and rhythmic movement induction
  • is critical for spatial learning
  • plays a critical role in regulating blood pressure through its actions on renal hemodynamics and epithelial ion transport, which are highly linked to its intracellular trafficking
  • concerted action of NPPA and DRD1 to regulate sodium homeostasis in nephrotic syndrome
  • facilitates relaxation in airway smooth muscle
  • DRD1 regulates the activity-dependent development of retinal light responsiveness
  • potential roles of DRD1 in the activity-dependent functional development of retina
  • dentate gyrus DRD1, but not DRD5, contribute to the formation of distinct contextual representations of novel environments
  • differential roles of DRD1 and DRD2 receptor-containing neurons of the nucleus accumbens shell in behavioral sensitization

    INTERACTION

    small molecule
    protein
  • calnexin interactions critically regulate DRD1
  • CALY interacting directly with DRD1, and is implicated in various neuropsychiatric disorders including schizophrenia, bipolar disorder, and attention deficit hyperactivity disorder
  • CALY interacts with DLG4 and subsequently forms a ternary complex with DRD1 through DLG4
  • interaction between DRD1 and NMDAR in synapses participate in the building of the dopamine-receptor-mediated signalling, and most likely to the glutamate-dopamine cross-talk
